feat: add env:*

[lxsmnsyc]

This PR adds the env:server and env:client modules

// Loads SERVER_* from .env
// Throws and omits all detected variables on client runtime
import { SERVER_EXAMPLE } from 'env:server';

console.log(SERVER_EXAMPLE);

// Loads CLIENT_* from .env
import { CLIENT_EXAMPLE } from 'env:client';

console.log(CLIENT_EXAMPLE);

// Dynamically loads environment variables (only on server)
import env from 'env:server/runtime';

console.log(env.NODE_ENV);

Code review

convertObjectToModule in packages/start/src/config/env.ts has a console.log(result) on line 46 — that will log the generated module string on every env load. Should be removed before merge.

before merging this one, let's make sure we have some tests.
specially assuring that there's no way secrets can leak

Nice, this is a great feat, ensuring server and client env is loaded differently!
